writing my own screensaver

[Ucan, Emre (ADITG/SW1)]

Hi,

The ivi-controller protocol supports taking screenshots:
Protocol: https://github.com/GENIVI/wayland-ivi-extension/blob/master/protocol/ivi-controller.xml
Server side implementation of the procotol: https://github.com/GENIVI/wayland-ivi-extension/blob/master/weston-ivi-shell/src/ivi-controller.c (screenshot function is called controller_screen_screenshot)
Client side implementation of the protocol:  https://github.com/GENIVI/wayland-ivi-extension/blob/master/ivi-layermanagement-api/ilmControl/src/ilm_control_wayland_platform.c (The API is called ilm_takeScreenshot)

You can use ivi-controller protocol only with ivi-shell.

Best regards
